Hi,

Opensuse still use classic Mesa driver for hardware acceleration on radeon driver ; there are actually 2 mesa drivers for radeon, r300 and r600, and both come with 2 version : classic Mesa (r300c and r600c) and Gallium3d Mesa (r300g and r600g).

Gallium drivers will be available in GNOME:STABLE:3.0 repository for 11.4 (when it is released, ie really soon now), since it is required by GNOME Shell.

I plan to discuss the switch for next openSUSE release with X team.

X team has just accepted the switch to gallium for radeon and r600 : package is rebuilding in X11:XOrg and will be submitted to factory soon. -- Frederic Crozat Novell -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org For additional commands, e-mail: opensuse-factory+help@opensuse.org

First of all I'd like to thank the openSUSE team for the X11:XOrg repository, with which I found a comfortable way to enjoy 3D acceleration with my HD 5450 (r600).

But the switch to Gallium driver feels really bad with my HD 5450. I'm running 11.3 (KDE and very few compositing effects).

Each screen update - even typing - seems to have a little delay before the screen update happens. Redraws of windows are slow and snatchy, the same effect can be seen with all movements on the screen. It seems that updates happen only approx. 10-20 times per second with visible pauses in between. The KDE desktop feels slow and makes me edgy.

Is it due to the immaturity of the r600g driver, or are there some important tuning knobs?

I guess it would be interesting to compare with 11.4 + gallium drivers and maybe also with F15beta. At least for GNOME 3, r600g is much better (stable and rendering) than r600. Check https://bugzilla.novell.com/show_bug.cgi?id=689194 because it looks like your issue. If not, open a new bug report. -- Frederic Crozat Novell -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org For additional commands, e-mail: opensuse-factory+help@opensuse.org

Window refresh is unacceptable slow with disabled compositing, even with classic Mesa. If I enable compositing it becomes real fast. This effect is not reproducible with Gallium3d Mesa, window refresh is always slow. Who is now the culprit? vblank_mode=0 doesn't help, it was disabled anyway. I'll test openSUSE 11.4 and Mesa 7.11, but give me some days to reply.
